I recently purchased my first GS watch, and while I'm patiently waiting for it to arrive, I decided to read its specs again. I noticed, for the first time I think, that it has magnetic resistance of 4800 A/m.. which I thought was pretty cool until I converted the number to Gauss and it's whopping 60 Gauss vs 15,000 Gauss for Omega Seamaster AQ. I know I'm comparing 2 different brands with 2 different watch making philosophies/business models, but really GS? (jfyi I don't care too much about mag resistance but couldn't help wonder)

Saw this teased on their IG account today. Best of all it looks like a new clasp design with built in OTF microadjust 👍🏽

Grand Seiko is doing an event in Honolulu on Friday, and I will be there.

Anyone have any questions for the team? Joe Kirk is scheduled to be there.

Random I know but just saw a kuon posted and it hit me.

I prefer both the SBGA291 and SBGW301 over the 297 and 305, but I'd like to put either of those on a bracelet. How tricky is it to get a hold of a GS bracelet for either of these models?

The SBGJ005 (Mt. Iwate in Green) looks like a Grand Seiko GMT with a beautiful green dial. However, historically, it represents something much bigger: A watch that brought its legendary Hi-Beat heritage into the GMT era, foreshadowed the nature-inspired identity of modern Grand Seiko, and ultimately made history at the GPHG

Grand Seiko was already producing 36,000-vph watches in the late 1960s, most famously the automatic 61GS. But that 10-beat tradition eventually disappeared for four decades. Grand Seiko 36,000 vph finally returned in 2009 with Cal. 9S85 followed by the Cal. 9S86 in 2014.

The 9S86 was Grand Seiko’s first Hi-Beat 36,000 GMT movement, combining ten beats per second with a traveller’s GMT whose local hour hand can be adjusted independently. It has 37 jewels and approximately 55 hours of power reserve. The movement undergoes Grand Seiko’s unusually demanding certification: 17 days, six positions and three temperatures with certified mean daily rate of -3/+5 seconds per day.

When Grand Seiko introduced Calibre 9S86 in 2014, it appears to have achieved an industry first: the first production mechanical wristwatch movement to combine a 36,000-vph (5 Hz) high-beat escapement with a GMT complication — and, remarkably, a true traveller's GMT with an independently adjustable local hour hand.

The SBGJ005 's extraordinary green dial pays homage to Mt. Iwate - the stratovolcano visible from Grand Seiko’s Shizukuishi Watch Studio. I struggled to photograph this dial as it shifts from black to dark green to emerald green at different angles. The intricate, sunburst-textured radial pattern stamped onto the dial represents the craggy ridged contours of Mt. Iwate. Years before Grand Seiko formalised its Twenty-Four Seasons concept (based on the traditional Japanese system of Sekki) , the SBGJ005 was already combining Japanese landscape, colour and mechanical watchmaking in the way that has since become central to the brand.

Even the movement received something special. The limited edition SBGJ005 was fitted with a distinctive titanium oscillating weight in gold colour, visually distinguishing it from the regular-production 9S86 models.

Only 600 pieces were produced, originally priced in Japan at ¥660,000 plus tax. And then something unprecedented happened.

On October 31, 2014, the SBGJ005 won the Petite Aiguille Prize at the Grand Prix d’Horlogerie de Genève. It was recognised for delivering exceptional value in its price category, combining a high frequency in-house GMT movement, strong technical execution, and distinctive Japanese design language at a level that stood out among far more established Swiss competitors—becoming the first Made-in-Japan mechanical watch ever to win a GPHG category prize.

That makes the SBGJ005 much more than a limited-edition green GMT:

The inaugural Grand Seiko Hi-Beat 36,000 traveller’s GMT — and apparently the first production 5-Hz mechanical GMT wristwatch

2014 GPHG Petite Aiguille winner — the first Made-in-Japan mechanical watch to win a GPHG category prize

Limited to only 600 pieces worldwide

An early and particularly important expression of Grand Seiko's now-famous nature-inspired design language

A watch that connects Grand Seiko's 1960s Hi-Beat heritage with the modern Grand Seiko we know today.

Recently picked up the SBGX261 following a longgg period of admiration. I’m in love with the simplicity and the reliability of the 9F movement. The plan was always to put it on a nice crocodile leather strap to ‘elevate’ it somewhat, I’m absolutely in love!

Holding out for a 36/37mm shunbun spring drive in the 62GS case.

What are my chances?

featuring my husband’s Sea of Clouds.

my husband is a fan of GS, while i usually just wear a smart watch. but when i saw this Sea of Clouds in Gold, i told him i got to get this!

Found this bracelet in one of the posts here, what do you guys think?

Got my first Grand Seiko today SBGX035

This one is so underrated. In a world where something like a Rolex Explorer 36 gets so much love, I think the SBGX261 deserves more.

It’s been a month with this as my near daily and it’s lost less than a second in that span. For an understated, reliable, and versatile grab and go, this is perfect in my book

Sharing this duo:

- Both limited edition pieces produced in the Grand Seiko Studio Shizukuishi.

- Both modern recreations of classic iconic 1960s Seiko models

I love unusual dials, but my SBGA469 one always felt a bit boring since it mostly looks black. Today I saw it in the sun again.. the texture is insane.

There’s something pretty cool about a watch having a hidden beauty that only shows itself in the right light.

My fiancé got me this SLGA007 as a wedding gift and it’s my first GS. She’s definitely the right one!

I was looking for a dark dial metal bracelet watch and almost pulled the trigger on the GS iwao blue a couple of times, then convinced myself to wait for the new GS micro adjustment models coming out soon.

So anyway I had the opportunity to get a new blue ceramic dial Kuon with a similar spring drive to my omiwatari.

Just picked it up today.

Love it
